Back in the 1970s and 1980s, real estate developers' favorite trick was pulling an atrium out of the inside of buildings. Now, architects and designers who've been charged with renovating these old buildings are trying to figure out what to do with all that wasted space. "There are so many of them, and it's a big challenge," said Barry Maners with Dallas-based design firm Entos. "Back in the '70s and '80s, every building had to have that big volume of space."

The 13-story, 112,225-square-foot boutique office tower at 3625 N. Hall St. - called Hall Street at The Centrum - will be transformed from the 35-year old tower into a sought-after destination for modern office space."

"Upgrades are in store for Mandalay Towers 1, 2 and 3 in the Las Colinas Urban Center. Parmenter has announced a multimillion-dollar plan to redevelop the three towers and will also redesign Mandalay Park, a 1-acre park located between the buildings. Together the buildings comprise more than 800,000 square feet, 50,000 square feet of which is marked for retail use...

...ENTOS Design will oversee the redesign of the buildings interiors, including a redesign of the Towers 2 and 3 lobbies and a renovated fitness center and conference room, among other changes."

Dallas-based ENTOS Design, which worked on the original tower upgrade, was hired to finish the remainder of the office complex. Plans include upgrading lobby areas, reorienting the conference center, upgrading the fitness center and putting in a tenant lounge to give the building a boutique feel. The plans also include revamping entryways and signage throughout the office complex. Construction is slated to get underway this summer."

"Mandalay Towers 1, 2 and 3 in Las Colinas' Urban Center are getting a major upgrade. The Las Colinas Association has approved Parmenter's multimillion-dollar redevelopment by interiors firm ENTOS Design. The work will be completed early this summer."

"The final touches of a $19 million renovation to the Galleria Towers — three-building, 1.4 million-square-foot Class A office complex — at the high-profile intersection of the Dallas North Tollway and LBJ Freeway are being put in place and it seems to be bringing in the corporate tenants...

Dallas-based ENTOS Design was the interior architect that oversaw the renovation project, which is already having an impact on the building's leasing program, said Fowden, a senior vice president of CBRE."
